I believe that I'll contribute another TX locale for hell.  Van Horn, TX. this little bit of hell is somewher in western TX.    When you get to Van Horn, it's been at least a 100 miles since you've seen another car.  when you leave the road is straigtht and flat for the next 100 miles complete with the reassuring sign "next services 93 miles".    
  
face it people,  if you've chosen climbing as your passion in life, TX is just unacceptable.  Why do you go there?
